I have the Lee Breechlock Challenger press, and love the breechlock inserts. I have them on all my dies. Once you set up a die, there is no need to set it up again, just 1/6 turn to remove, and install.
You can also leave a breechlock insert in the press, and it is just like a normal press.
Primer disposal works just fine, too
What are 1 1/4 dies used for?
